    Motorola MVME162-522A Single Height 6U VME SBC (32MHz MC68040 FPU, 8MB DRAM, Ethernet + SCSI + 512KB Battery SRAM)
    Manufacturer: Motorola Embedded Systems (Later Emerson Embedded Computing)
    Model: MVME162-522A
    Series: MVME162 Single Height 6U VME Single Board Computer Family
    Type: Top-tier single-height VME master CPU board, MC68040 32MHz with integrated FPU, full integrated Ethernet + SCSI + 512KB battery-backed SRAM, max 8MB parity DRAM
    Function: Heavy-load real-time embedded master computing node for Honeywell TDC3000 HM/Global Operator Stations, power plant, offshore, railway, defense VME rack systems; dual configurable serial ports, 4×IndustryPack expansion slots, full A32/D64 D64 VME bus master, multi-stage hardware watchdog, battery-backed RTC/NVRAM; compatible with VxWorks, OS-9, pSOS+, LynxOS, OpenBSD/mvme68k RTOS
    1. Overview
    MVME162-522A is the highest-spec single-height 6U VME SBC in the entire MVME162 product line, following Motorola’s unified naming rule: - 5xx series = 32MHz MC68040 with FPU; - 2xx suffix = 8MB maximum parity DRAM; - x2x suffix = onboard 10/100 Ethernet + narrow SCSI dual interfaces; - xxA = industrial wide-temperature reinforced version (-40℃ ~ +85℃). It retains single-height 6U mechanical form factor with four IndustryPack expansion slots (key difference vs dual-height MVME162-220 which removes IP slots). Equipped with 32MHz MC68040 CPU with built-in FPU floating-point arithmetic unit, supporting high-precision complex process control algorithm calculation. Standard full configuration: 8MB parity-protected shared DRAM, fixed 512KB high-speed battery-backed SRAM, 1MB onboard firmware Flash, integrated Intel 82596CA 10/100Mbps Ethernet, NCR53C710 narrow SCSI storage controller, dual RS232/422 configurable serial ports, MK48T08 8KB NVRAM & TOD real-time clock, multi-level hardware watchdog timer, 8-channel front panel status LEDs and manual RESET/ABORT buttons. Widely deployed as main HM/Global Station computing core for legacy Honeywell TDC3000 DCS, balancing high memory capacity, floating-point performance, native network/storage interfaces and flexible IndustryPack I/O expansion capability. Full A32/D64 D64 VME bus master & DMA burst transmission for high-speed cross-board data exchange.

    3. Core Model Comparison (MVME162 High-End Series)
    1. MVME162-512A: 32MHz FPU, 4MB DRAM, Ethernet+SCSI+512KB SRAM, single-height, 4×IP slots, 0~70℃
    2. MVME162-522A: 32MHz FPU, 8MB DRAM (max single-height), Ethernet+SCSI+512KB SRAM, single-height, 4×IP slots, -40~85℃ wide temp A version
    3. MVME162-220: 25MHz FPU, max 8MB DRAM, Ethernet+SCSI+512KB SRAM, dual-height, NO IP expansion slots, 0~70℃
    Positioning: -522A = single-height full-performance wide-temperature flagship; -220 = dual-height maximum memory without IP expansion; -512A = mid-range single-height high-performance node
